specific Embodiment approach

[0033] A method for processing printed board holes includes 1] drilling according to a drilling file; 2) preparing a milling file; 3] milling a hole according to the milling file. Among them, step 2] can be carried out as follows:

[0034] Manually import the drilling file to be converted into milling holes, and the system will pop up a dialog box (see figure 2 ), input or select the following drilling to milling parameters:

[0035] 1. According to the processing capacity of the drilling process, enter the minimum diameter of the hole to be converted to milling;

[0036] 2. Enter the diameter of the milling cutter. This parameter determines the tool allowance of the milling program generated by the program. It can also be set to 0. The tool allowance can be flexibly set when milling holes;

[0037] 3. Enter the name of the exported milling hole file;

[0038] 4. Choose whether to convert 3.175 holes into milling holes. Since 3.175 holes are generally milling plate positioning holes a...

Abstract

The invention relates to a method for machining holes in printed boards. The method includes 1), drilling the holes according to drilling files; 2), preparing hole milling files; 3), milling the holes according to the hole milling files, and the like. The method has the advantages that when the hole milling files are prepared in the step 2), preliminarily compiled macro-programs are invoked by the aid of macro-language in CAM (computer-aided manufacturing)350 software, and only drilling-to-hole-milling switching parameters need to be inputted and selected, so that the hole milling files can be automatically generated, the hole milling machining efficiency and accuracy can be greatly improved, and human errors due to manual operation can be eliminated.

Description

Technical field [0001] The invention belongs to the field of printed board manufacturing and relates to a method for processing printed board holes. Background technique [0002] With the rapid development of printed boards, the components on the printed boards are becoming more and more dense, and the heat dissipation per unit area is also increasing. High-density printed boards must use high Tg plates to meet the heat resistance requirements. The high Tg sheet increases the glass transition temperature of the sheet, while at the same time the hardness of the sheet increases and the toughness decreases. When drilling a larger hole, white spots are often generated on the edge of the hole, resulting in an increase in the scrap rate of the drilling process. [0003] After experiments, the method of milling holes for larger holes will not produce white spots on the edges of the holes. However, this will add a milling process after drilling. [0004] To mill a hole, you need to genera...
